The character " / " generally indicates that the previously associated objects are in an "or" relationship.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0028] Headphones are one of many types of headphones. Headphones are worn on the head, not inserted into the ear canal, and are different from in-ear earplugs. Because headphones are wrapped around the outside of the ear during use, they have the advantages of good sound field, very good sound quality, and good comfort. Headphones can be divided into wired or wireless types. They also have a cool feeling when worn, and are also loved by young consumers.

[0029] Headphones generally include a headband and two speaker assemblies. In order to make different wearers feel comfortable when wearing the headphones, a sliding belt is generally provided. The sliding belt passes through the end of the headband and slides freely inside the headband. The speaker assembly is provided at one end of the sliding belt, so that as the sliding belt slides, the speaker assembly also slides and adjusts together, thereby adjusting the size of the headphones.

[0030] However, although the size of existing headphones can be adjusted by sliding straps, the adjustable size is mostly limited to the distance between the speaker assembly and the top of the headband. After the size of the headphones is adjusted to the right size, the clamping force during wearing is relatively fixed. However, the size of each person's head circumference is different. When the clamping force of a single speaker assembly cannot be adjusted, the wearing comfort needs to be improved.

[0031] To solve the above problems, please refer to Figure 1 and Figure 2 The present application proposes a headset 1. In an embodiment of the present application, the headset 1 includes a headband 10, two sliding arm assemblies 20, two earphone monomers 30 and an adjustment structure 40.

[0032] The headband 10 has an overall arc-shaped structure, which provides elastic clamping force for the entire headset. The headband 10 may include two parts: a frame and a covering structure. The covering structure is wrapped around the outside of the frame. The frame may be made of elastic plastic or metal, and the covering structure may be made of soft materials such as leather and cloth.

[0033] The two sliding arm assemblies 20 are respectively connected to the two ends of the headband 10, and the sliding arm assemblies 20 and the headband 10 enclose a wearing space 10a. The sliding arm assembly 20 includes a first part 21 and a second part 22. The first part 21 is slidably connected to the headband 10 so as to be retractable relative to the headband 10. An earphone unit 30 is connected to the second part 22 in a sliding arm assembly 20. The first part 21 and the second part 22 can be rotatably connected via a rotating shaft, that is, the first part 21 and the second part 22 can rotate relative to each other around the axis of the rotating shaft. The axis of the rotating shaft can be configured to be perpendicular to the rotation plane of the first part 21 and the second part 22. Of course, the rotation connection form of the first part 21 and the second part 22 can also be other, such as a hinge connection, etc., and the present application does not limit this. The first part 21 and the second part 22 are rotatably connected via a rotating shaft and can be configured to enable the second part 22 and the earphone unit 30 to swing together into the wearing space 10a. In this way, the rotatable connection between the first part 21 and the second part 22 can realize the storage function of the headphone 1 of the present application during use, so that the volume of the entire device is smaller after storage.

[0034] In one embodiment, the earphone unit 30 includes a speaker assembly 31, an ear shell 32 and a bracket 33. The speaker assembly 31 is placed in the ear shell 32. The ear shell 32 is rotatably connected to the bracket 33. The bracket 33 is rotatably connected to the second part 22. An earmuff assembly 34 is fixed to the ear shell 32. The earmuff assembly 34 can improve the comfort during wearing and improve the sound quality. In this embodiment, by rotatably connecting the bracket 33 to the ear shell 32 and the bracket 33 to the second part 22, the earphone unit 30 can be located as much as possible in the wearing space 10a when the headphone 1 is in the storage state, thereby reducing the volume in the storage state.

[0035] As for the sliding connection between the first portion 21 and the headband 10, in one implementation form, a sliding cavity 101 may be formed inside the headband 10 (see Figure 3 ), one end of the first part 21 extends into the sliding cavity 101 and is slidably connected to the headband 10. It can be understood that the setting of the sliding arm assembly 20 can adjust the distance between the earphone monomer 30 and the top of the headband 10 during the use of the headphone 1, so that the position of the earphone monomer 30 can be matched with the position of the ear of users with different head sizes. In order to keep the adjusted position of the earphone monomer 30 relatively stable, the present application can further provide a slot 102 and a latch tooth 231 between the first part 21 and the headband 10. Through the engagement of the latch tooth 231 and the slot 102, the adjusted earphone monomer 30 can be prevented from shifting under a small external force impact, thereby improving the convenience of wearing.

[0036] The above content describes one implementation of the sliding connection between the headband 10 and the sliding arm assembly 20. It is understandable that the specific form of the headband 10 in the present application can also be other forms, and the specific sliding connection form of the headband 10 and the sliding arm assembly 20, in addition to the above embodiments, can also be a sliding cavity 101 formed in the first part 21, and a part of the structure of the headband 10 is inserted into the sliding cavity 101 of the first part 21, or the headband 10 and the first part 21 are relatively slidable through a sleeve, etc. The present application does not limit this.

[0037] For different people, the distance between the ear and the top of the head may be the same, but the head circumference is different. After the earphone unit 30 is stretched to match the ear position of the user, in order to obtain a better wearing comfort, the people also have a need to adjust the clamping force of the structure composed of the headband 10 and the sliding arm assembly 20. To this end, please refer to Figure 4 The adjustment structure 40 of the present application is movably connected to the first part 21. The adjustment structure 40 is located on the side of the shaft away from the headband 10, and can push the second part 22 so that the second part 22 can drive the earphone monomer 30 to rotate relative to the first part 21, thereby changing the distance between the two earphone monomers 30.

[0038] It can be known from Hooke's law that F=KX. Under the premise of not changing the elastic coefficient, F can be adjusted by adjusting the deformation distance. The arc structure composed of the headband 10 and the sliding arm assembly 20 provides clamping force for the entire headphone 1, and drives the earphone monomer 30 to cover the outside of the wearer's ear with elastic clamping characteristics. During the wearing process, the user's head causes the distance between the two earphone monomers 30 to change, and the two earphone monomers 30 further cause the arc structure composed of the headband 10 and the sliding arm assembly 20 to produce elastic deformation due to the force. Therefore, the change range of the distance between the two earphone monomers 30 from the unworn state to the worn state is positively correlated with the elastic deformation range of the arc structure composed of the headband 10 and the sliding arm assembly 20.

[0039] Therefore, the purpose of the present application by setting the adjustment structure 40 is that, for different users, the distance between the two ears is different. The scheme of the present application can adjust the distance between the two earphone monomers 30 during wearing, causing the arc structure composed of the headband 10 and the sliding arm assembly 20 to produce a suitable elastic deformation amplitude, thereby obtaining a clamping force with a more comfortable feeling. For example, for users with a smaller head circumference, the distance between the two ears is slightly smaller. By pressing the second part 22 with the adjustment structure 40, the second part 22 drives the earphone monomer 30 to rotate equivalent to the first part 21, that is, swinging into the wearing space 10a, thereby reducing the distance between the two earphone monomers 30. In this way, the elastic deformation amplitude of the arc structure composed of the headband 10 and the sliding arm assembly 20 is increased during wearing, compared with the scheme of earphones without adjustment function. In this way, the clamping force of the present application is increased after adjustment, so that a suitable clamping force can be obtained to improve wearing comfort. Of course, in some actual usage scenarios, users may also want to obtain a relatively larger clamping force. For example, when running, users hope to obtain a larger clamping force than in normal use, so that the earphones can be worn more firmly and not fall off easily. This can also be achieved through the above operation method.

[0040] Therefore, based on the headset 1 of the embodiment of the present application, by setting a sliding arm assembly 20, the earphone unit 30 is connected to the sliding arm assembly 20, and the size can be roughly adjusted during wearing by extending and retracting the sliding arm assembly 20 relative to the headband 10, so that the headset 1 can adapt to users with different head sizes.

[0041] The present application also configures the sliding arm assembly 20 to include a first part 21 and a second part 22 rotatably connected to the first part 21, and further provides an adjustment structure 40 movably connected to the first part 21. The second part 22 is pushed by the adjustment structure 40, so that the earphone monomer 30 can be driven by the second part 22 to rotate relative to the first part 21, thereby changing the distance between the two earphone monomers 30 to achieve fine-tuning. Through the above settings, the headphone 1 of the present application can be accurately adapted to users with different head circumferences, with a more matched clamping force and higher wearing comfort.

[0042] At least part of the structure of the adjustment structure 40 of the present application is movably connected to the first part 21, so that when the adjustment structure 40 moves relative to the first part 21, it can push the second part 22, thereby driving the earphone unit 30 to move toward the wearing space 10a, thereby fine-tuning the distance between the two earphone units 30 and reducing it.

[0043] The adjustment structure 40 can be moved relative to the first part 21 by electric means, for example, by using a motor, an electric cylinder, etc. as a power element. Of course, it can also be achieved manually, where the user operates the adjustment structure 40 to cause at least part of the adjustment structure 40 to move relative to the first part 21 and thus push the second part 22.

[0044] In the implementation method of manual adjustment, the first part 21 may be provided with an adjustment hole 241, and the adjustment structure 40 may include an adjustment member 41, and the adjustment member 41 may be movably arranged at the adjustment hole 241; specifically, the adjustment member 41 includes an operating part 42 and a supporting part 43 connected to each other, the operating part 42 is exposed on the first part 21, and the supporting part 43 is at least partially located between the first part 21 and the second part 22, and is supported on the second part 22.

[0045] During use, when the user exerts force on the operating portion 42 , the abutting portion 43 is driven by the operating portion 42 to move along the adjusting hole 241 and drive the second portion 22 to rotate.

[0046] In this embodiment, the adjustment hole 241 is provided to realize the installation of the adjustment structure 40, so that the adjustment structure 40 can hide most of the structure in the first part 21. In this way, on the one hand, the adjustment structure 40 is effectively installed and fixed, and on the other hand, the appearance of the headset 1 is more consistent and more beautiful. It can be understood that by providing the adjustment hole 241, the user can manually adjust the operating part 42 without adding other external power components, and the overall cost is low.

[0047] Further, in any of the above embodiments, for the convenience of assembly, the first part 21 includes a sliding arm 23 and a cover body 24, the sliding arm 23 is slidably connected to the headband 10, the cover body 24 is fixedly connected to the sliding arm 23 and spliced ​​to the end of the headband 10, and the adjustment structure 40 is connected to the cover body 24, that is, the adjustment hole 241 is provided on the cover body 24. When the sliding arm 23 is received in the headband 10, the cover body 24 contacts and splices with the end of the headband 10. In this way, the above-mentioned adjustment structure 40 can be installed on the cover body 24, and then assembled as a whole to the sliding arm 23 that has been assembled with the headband 10. In this way, the assembly reference is easier to determine, the assembly efficiency is higher, and the later maintenance is more convenient, and there is no need to disassemble the sliding arm assembly 20 as a whole. It can be understood that the sliding arm 23 and the cover body 24 of the present application can be a split structure. The two can be detachably connected, for example, fixedly connected by a snap connection, a screw connection, etc., or a detachable connection form that requires destroying the structure, such as a fixed connection by welding, bonding, etc. In addition, the sliding arm 23 and the cover body 24 can also be an integral structure, for example, formed as an integral structure by injection molding.

[0048] Please refer to Figure 5 and Figure 6 In the first embodiment of the adjusting member 41, the abutting portion 43 of the adjusting member 41 includes a push rod 45 and a pin 46 fixed on the push rod 45. The push rod 45 is inserted into the adjusting hole 241 and can rotate around its own axis in the adjusting hole 241. One end of the push rod 45 is connected to the operating portion 42, and the other end abuts against the second portion 22.

[0049] An annular platform 25 is provided on the cover body 24 or the second part 22. The annular platform 25 is provided around the opening periphery of the adjustment hole 241. The annular platform 25 is provided with recesses 252 and protrusions 251 at intervals along the circumferential direction. During the rotation of the push rod 45, the pin 46 abuts against the protrusion 251 or is embedded in the recess 252.

[0050] In this embodiment, the movement mode of the adjusting member 41 in the adjusting hole 241 is rotation and axial extension and contraction, wherein the outer diameter of the operating portion 42 is larger than the outer diameter of the adjusting hole 241 and is exposed on the outer surface of the cover body 24. In the specific assembly process, the operating portion 42 is held by hand to insert the push rod 45 into the adjusting hole 241 and abut against the surface of the second part 22, and the pin 46 is fixed at the position where the push rod 45 is located between the cover body 24 and the second part 22, thereby the pin 46 also cooperates with the operating portion 42 to limit the entire adjusting member 41 on the cover body 24. It can be understood that the position where the push rod 45 of the present application abuts against the second part 22 is on the side of the second part 22 away from the position where the second part 22 is rotatably connected to the cover body 24. During use, when the distance between the two earphone monomers 30 needs to be reduced, force can be applied to the operating part 42 to drive the adjustment part 41 to rotate, so that the pin 46 stays on the protrusion 251. In this way, the push-up action of the protrusion 251 makes the push rod 45 push out toward the second part 22, and then the second part 22 carries the earphone monomer 30 to swing a small distance into the wearing space 10a, thereby reducing the distance between the two earphone monomers 30.

[0051] It can be understood that the rotatable form of the adjusting member 41 in this embodiment has multiple advantages such as stable structure, convenient assembly and low cost.

[0052] Furthermore, in the above embodiment, the adjustment structure 40 further includes an elastic member 44, the two ends of which are respectively in contact with the pin 46 and the cover 24; the elastic member 44 is used to provide elastic force to drive the top rod 45 to have a movement tendency away from the second part 22. The elastic member 44 can be in the form of a spring, a spring sheet, etc. In the structure exemplarily shown in the figure, the elastic member 44 is a spring, which can be sleeved on the top rod 45 before fixing the pin 46. In this embodiment, through the provision of the elastic member 44, when the pin 46 moves to the concave portion 252 and the convex portion 251, it can stay stably due to the outward tension, and it is not easy to shift.

[0053] In order to further improve the stability of the pin 46 staying on the protrusion 251, the present embodiment may further provide a limiting groove 253 on the protrusion 251, and the limiting groove 253 is used for the pin 46 to be embedded when the pin 46 moves to the boss.

[0054] It is understandable that the elastic member 44 can enhance the stability of the pin 46 and the annular platform 25, but the elastic member 44 may not be provided if the friction between the annular platform 25 and the pin 46 can also achieve a stabilizing effect through the material selection. Alternatively, in the case where the elastic member 44 is provided, the elastic member 44 can provide the push rod 45 with a movement tendency away from the second part 22, and the specific connection position of the elastic member 44 may also be other, and the present application does not limit this.

[0055] Please refer to Figure 7 and Figure 8 In the second embodiment of the adjusting member 41, the adjusting member 41 includes a toggle portion 42a and a push portion 43a, the push portion 43a includes a sliding portion 47 and a push protrusion 48 connected to each other, the toggle portion 42 is penetrated through the adjusting hole 241, and is respectively connected to the push protrusion 48 on opposite sides of the sliding portion 47; wherein the sliding portion 47 is slidably matched with the cover body 24, and the second portion 22 is provided with an avoidance groove 221, when the sliding portion 47 slides relative to the cover body 24, the push protrusion 48 enters the avoidance groove 221, thereby increasing the distance between the two earphone monomers 30, and the push protrusion 48 withdraws from the avoidance groove 221, thereby reducing the distance between the two earphone monomers 30.

[0056] The difference between this embodiment and the previous embodiment is that the adjustment member 41 is slidably connected to the cover body 24. The adjustment hole 241 of this embodiment is an elongated hole, and its long axis direction is consistent with the sliding direction of the adjustment member 41. The adjustment hole 241 mainly plays a guiding and limiting role. During use, the user applies force to the exposed toggle portion 42 to drive the sliding portion 47 to move, so that the top-butting convex portion 48 switches between the state of entering the avoidance groove 221 and exiting the avoidance groove 221, thereby adjusting the distance between the two earphone monomers 30. The entire structural form also has multiple advantages of stable operation, convenient operation, and low cost.

[0057] In order to ensure that the sliding part 47 can stably maintain this position when the push-butt protrusion 48 enters the avoidance groove 221 or exits from the avoidance groove 221, the pushing part 43 of this embodiment also includes a limiting protrusion 49 connected to the sliding part 47, and the cover body 24 is also provided with a positioning groove 262. The limiting protrusion 49 is embedded in the positioning groove 262 in any state where the push-butt protrusion 48 is embedded in the avoidance groove 221 or exits from the avoidance groove 221.

[0058] In this embodiment, the positioning groove 262 is set on one side of the adjustment hole 241, and at least two are arranged in sequence on the sliding path of the sliding part 47, so that the top-butting protrusion 48 can be embedded in the positioning groove 262 in any state of being embedded in the avoidance groove 221 or withdrawn from the avoidance groove 221, thereby achieving the positioning effect.

[0059] Please refer to Figures 9 to 11 Furthermore, a retaining rib 26 is protrudingly provided on the surface of the cover body 24 facing the second part 22. The retaining rib 26 is arranged around the adjustment hole 241 and cooperates with the surface of the cover body 24 to define a slide groove 261. The sliding portion 47 is slidably arranged in the slide groove 261, and the positioning groove 262 is arranged on the retaining rib 26. In this embodiment, since the sliding portion 47 is located between the cover body 24 and the second part 22, the retaining rib 26 is used to form the slide groove 261 to achieve the installation of the sliding portion 47. Under the multiple limiting effects of the cover body 24, the second part 22 and the retaining rib 26, the assembly structure of the sliding portion 47 is relatively stable. The above installation form of the sliding portion 47 also makes the overall structure relatively simple and reliable.

[0060] The above content illustrates two forms of rotational cooperation and sliding cooperation between the adjusting member 41 and the adjusting hole 241. It can be understood that, based on the provision of the adjusting hole 241, in this embodiment, the adjusting member 41 and the adjusting hole 241 can also be set as a threaded connection, and the second part 22 can be abutted by rotating the adjusting member 41. Alternatively, the present application may also be that the adjusting hole 241 is not provided, and the adjusting structure 40 is directly slidably connected to the cover body 24. At this time, the adjusting member 41 can be sleeved on the structure of the cover body 24, or a slide groove 261 structure can be provided on the structure of the cover body 24 to realize the sliding installation of the adjusting member 41. For this reason, the present application does not make any specific restrictions.

[0061] It should be noted that the headset 1 of the present application may be provided with an adjustment structure 40 corresponding to the earphone monomer 30 on one side, and the specific form of the adjustment member 41 in the adjustment structure 40 may adopt any of the above-mentioned embodiments. In addition, the headset 1 of the present application may also be provided with an adjustment structure 40 corresponding to the earphone monomers 30 on both sides, that is, the earphone monomers 30 on both sides can be distance-adjusted, and the specific implementation form of the adjustment structure 40 may refer to any of the above-mentioned embodiments.

[0062] The same or similar numbers in the drawings of this embodiment correspond to the same or similar parts; in the description of this application, it should be understood that if the terms "upper", "lower", "left", "right", etc. indicate an orientation or position relationship based on the orientation or position relationship shown in the drawings, it is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the terms describing the position relationship in the drawings are only used for illustrative purposes and cannot be understood as a limitation on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0063] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
